They would like to have the users complete survey questions through the community interface and store the responsesin a Custom Object that has a lookup to the account object. Any internal user who has access to the account should be able to see all survey responses. All Customer Community users should be able to see surveys filled in by other users for their company,but not surveys for other companies. What are the correct security settings to achieve this?
